Imaging of the morphological and biochemical composition of the deep articular cartilage has important implications in the assessment of osteoarthritis. The deep cartilage layer has intrinsically short T2* characteristics and ultra-short echo time (UTE) imaging techniques have been recently employed in the depiction of the deep cartilage layer morphology. UTE imaging is known to be affected by k-space trajectory errors. The purpose of the present work is to investigate the effect of trajectory errors in UTE imaging used for the depiction and relaxometry of deep articular knee cartilage. A GIRF-correction is applied to correct eddy-currents induced k-space trajectory errors.
